Automatic switching device for water-lifting aeration equipment and bottom oxygenation mixed equipment

Abstract

The invention discloses an automatic switching device for water-lifting aeration equipment and bottom oxygenation mixed equipment. The switching device comprises a valve box body, an air inlet and two air outlets, wherein a switching plate which can rotate fixedly around a rotating shaft is arranged in the valve box body, a partition plate is arranged above the rotating shaft which is arranged onthe switching plate, the switching plate and the partition plate divide the internal space of the valve box body into a left air chamber, a right air chamber and an air distribution chamber, one air outlet is formed on the upper part of the left air chamber, the other air outlet is formed on the upper part of the right air chamber, and the air inlet is positioned on one side of the space of the air distribution chamber; and a baffle which is used for keeping the switching plate horizontal is positioned on the upper part of the switching plate at the bottom of the left air chamber and is fixedon an inner wall of the valve box body. The device is arranged at the tail end of an air transmission main pipe, the large-flow and small-flow air outlets are connected with the water-lifting aeration equipment and isothermal layer oxygenation mixed equipment respectively, and air is supplied to two kinds of in-situ water quality remediation equipment by using the same air transmission main pipe,so that the investment cost and operating cost of the air transmission main pipe are reduced.

Description

technical field [0001] The invention belongs to the field of water quality pollution control of water sources and reservoirs, and relates to an automatic air flow switching control device, in particular to an automatic switching device for pumping aeration and bottom oxygenation mixing equipment. Background technique [0002] Water source reservoirs and lakes have the characteristics of large capacity, large water depth, and low fluidity, which makes the water bodies of reservoirs (lakes) prone to stratification, resulting in relatively static between the upper and lower water bodies. This will result in the reduction of dissolved oxygen in the lower water body, the deterioration of the ecological environment of the bottom water body, and the release of nitrogen, phosphorus, organic matter, iron, manganese and other pollutants in the sediment into the water body. Due to the low fluidity, algae can stay in the surface water stably, receive sufficient light and reproduce in la...
